Title: New or improved means for testing the static balance of bodies
IPC: G01M1/12
Filed: 1950-07-18
Abstract: 694,648. Testing balance of rotary apparatus. JACKSON, E. R. July 31,1951 [July 18,1950], No. 17909/50. Class 106 (ii). Apparatus for testing the static balance of bodies which are symmetrical about an axis comprises a substantially cylindrical chamber open at its lower end and freely supported with its axis vertical in a bath of oil or other liquid by a volume of air or other gas trapped between the surface of the liquid in the chamber and a transverse partition which is adjacent to the upper end of the chamber and on which the body to be tested is mounted, means being provided to indicate the angular position and amplitude of any deflection of the axis of the chamber. The body to be tested is mounted on the top of a cylindrical member 30 having a tapered lower portion and being closed near the top by a partition 36. The member 30 floats in oil contained in a tank 31 by virtue of air or other gas trapped beneath the partition. To vary the sensitivity of the apparatus the amount of air trapped may be varied by a pump connected to a tap 39 communicating through pipes 37, 38 with the space above the liquid level in the member. A cord 33 or the like secured centrally to the partition and base of the tank normally maintains the member in the centre of the tank. If the test body is out-of-balance, the member 30 will tilt, the amount and direction of tilt corresponding with the size and angular position of the out-of-balance force and being indicated on a circular scale 46 by a light beam reflected by a mirror 40 on a flange secured to the member 30 and by a mirror 45. The space between the tank 31 and an outer casing 32 may be filled with heat-insulating material. In place of the cord 33, the partition 36 may carry a downward boss formed with a pair of ribs at right-angles to one another which co-operate with grooves in another boss normally lowered to an inactive position but capable of being raised by a hand-lever to centre and support the member 30 while the test object is mounted thereon. The boss has a central recess to receive a spindle or the like on the test object or a pin for co-operation with an axial recess in the object.

Filed: 1976-05-05
Abstract: 1506072 Cooking food CHEMETRON CORP 5 May 1976 [5 May 1975] 18437/76 Heading A2E [Also in Divisions A4 G3 and H5] Food is prepared for reheating in a microwave oven by selectively shielding the food items e.g. by wrapping in perforated metal foil whose apertures 194 &c. control the amount of radiation absorbed or by shaping the food items to change their surface area to volume ratio. Cooking time is automatically controlled by integrating a signal proportional to the microwave energv level in the heating cavity and switching off when a predetermined level has been reached. Larger food items which absorb more radiation are thereby given a longer heating time than small items. Heating may take place in two or more periods separated by intervals during which the temperature equalises throughout the item. Heating cycles for soup, fried chicken, mixed vegetables, mashed and boiled potatoes, scrambled egg, sausage, salisbury steak, denver sandwich and coffee cake are given.

Title: Improvements in or relating to sound translating devices
IPC: H04R1/40
Filed: 1939-06-26
Abstract: 530,483. Telephone instruments and circuits. ELECTRICAL RESEARCH PRODUCTS, Inc. June 26, 1939, No. 18521. Convention date, June 30,/1938. [Class 40 (iv)] A sound-translating device comprises the combination of a pressure-responsive moving- coil microphone 25 and a velocity-responsive microphone 49 arranged so as to have a substantially unidirectional response characteristic. The microphones have a generally coarsely curved exterior contour whereby each microphone allows sound waves to reach the other with a minimum diffractive effect. A casing 11 is mounted on a forked member 12 rotatable in a support 13 and the microphones are mounted within the casing by means of a bracket with arms 16 attached to the member 12 and upwardly extending brackets 18 to which the casing 27 of the moving-coil microphone is attached. The casing 27 is formed with a recess 54 in which is located a U-shaped magnet 40 which with a secured U-shaped magnet 39 is associated with pole-pieces forming an elongated gap for a ribbon diaphragm 49. The diaphragm is preferably corrugated near its ends and is convexly curved as indicated in Fig. 5. On the inner side of the gap 82 of the moving-coil microphone is located an apertured plate 83 carried by a sheet 85 of fabric. A flexible tube 37 connects the interior of the moving-coil microphone to the exterior to provide phase equalization at low frequencies. The casing of the moving-coil microphone houses an inductance 33, a transformer 31 and a condenser 34. In .the circuit arrangement shown in Fig. 4 the ribbon microphone is connected to the primary winding of the transformer 31 and the moving- coil microphone is connected to the secondary winding 68 provided with adjustable tappings 72 for varying the voltage output. The inductance 33 acts as a low frequency damping means for the ribbon unit and the circuit comprising essentially the condenser 34 and the tertiary winding 67 of the transformer is utilized to effect high frequency equalization by reducing the response of the ribbon unit at and above frequencies of say 3,000 cycles per second at which the moving-coil unit becomes increasingly directional. The switches 69, 70, 71 allow the units to be operated singly with or without the inclusion of the filter circuit. Specification 461,234 is referred to.

Abstract: 577,482. Electromagnetic interrupters. ERICSSON TELEPHONES, Ltd., and DISTIN, L. S. Sept. 28, 1944, No. 18542. [Class 38 (v)] In an electromagnetic interrupter one or more moving contacts 11 are resiliently attached to a vibratory reed 1 and normally positioned by rigid buffer members 14 fixed to the reed. The arrangement shown comprises a pair of reeds 1, one situated behind the other, coupled near their free ends by the armature 4. The magnetic circuit consists of a polepiece 6, a yoke 7 and a member 8. A non-magnetic member 9 is provided for rigidity. Attached to one of the reeds is a contact spring 15 which engages with a contact screw 16. Contact is broken when the armature is attracted by the magnet polepiece, so that vibration of both reeds is maintained in the usual manner. Adjustable weights or nuts 21 attached to posts, which may be threaded, on the top of the reeds enable the frequency to be varied. In a modification each reed carries its own armature and while both reeds still have the same natural frequency, the one which carries the driving contact is stiffer and more heavily loaded than the other. The reeds may in this case be coupled by a light spring. Specification 556,990 is referred to.
